Human Verification Options variable

[veenuisthebest]

Hii..

With 3.8.0, the Human verification options have been changed to checkboxes from option buttons, as in the attached pic.

Earlier, to check if register option was enabled I simply used $vbulletin->options['hvcheck_registration'], but this variable isn't available anymore.

There is just one variable for the whole setting which is $vbulletin->options['hvcheck']. So, how do I check if register option is check marked.

Thanks
